ACETYLENE-LAMP.

Specification of Letters Patent.

Patented Feb. 19, 1918.

Application filed July 14, 1915. Serial No. 39,881.

To all whom it may concern Be it known that I, JAMEs Bnocnnn, a citizenof the United States, residing at the city of Collinsville, Madisoncounty, Illinois, have invented a new and useful AcetyleneLamp, of whichthe following is a specification.

This invention relates to improvements in acetylene lamps, and moreparticularly to that type of acetylene lamps using gas generated by amixture of chemicals effective for the production of gaseous fuel, forinstance acetylene gas generated from the mixture of carbid and water. I

An object of the invention is to improve the construction of acetylenelamps of the type described with provision of a simple, unitarystructure including duplicate burners and independent gas generatingmeans, so that if one means for generating the gas becomes disabled, theother may be utilized under such emergency for the purpose ofillumination.

To the foregoing end as well as the attainment of the specificadvantages which will be apparent to those skilled in the art from thefollowing detailed disclosure without specific mention I have designedand arranged the structure clearly illustrated in the drawing to whichreference is made and in which:

Figure 1 is a plan view of an acetylene lamp including the presentinvention.

Fig. 2 is a side elevation of the lamp, further illustrating theconstruction: and,

Fig. 3 is a vertical section through the lam taken substantially on theline 3-3 of Fig. 1.

In the embodiment of the invention illustrated in the drawings the lampis shown as including a container A comprising a side wall 1, a bottomwall 2 and a top 3, preferably formed integrally and from spun metalsheeting. A hook 4 or other suitable device is attached to the side wall1 for the purpose of removably mounting the lamp in position in theusual manner upon a can or other suitable support.

The container A is divided into two compartments B and C respectively,by a cylindrical wall 5 fitted within the container A. Through the topwall 3 and over the compartment B of the container A is an opening 6which is embraced by an lip-standing annular flange 7. A cup-shaped cap8 provided with a. horizontal flange 9 is pivoted upon the top wall 3,the pivot connection including a bracket 10 and a strap 11. Thisconstruction provides a movable closure for the opening 6 and, as theparts are secured together by the pivot connection, the closure isalways maintained in position, so that. access to the compartment B maybe attained for the introduction of water or other fluid into thecompartment and the closure readily replaced after the chamber has beenfilled. in order to permit the flow of the fluid from the compartment Band to prevent the forming of a vacuum in the upper part of thecompartment a perforation 12 is provided in the closure.

Through the top wall 3 above the compartment C is an opening 13 which.is embraced by an outwardly extending annular flange 1%. The upper partof the wall 5 is bent to form threads 15 and is adapted to receive inthreaded engagement the side wall 16 of a compartment D. 1

The compartment D includes the side wall 16, a bottom wall 17 and a topwall 18 formed preferablv in integral construction from spun sheetmetal, and forms'a separate container adapted to receive a fluid. Anopening 19 in the top wall 18 provides means of access to thecompartment D and is embraced by an Lip-standing flange 20 adapted toreceive a pivoted closure 21, similar in construction and mounted in asimilar manneras is the closure 8.

In order to form a hermetic seal of the joint between the upper portionof the wall 5 and the wall 16 of the compartment D a rubber washer orgasket 22 is interposed between the inner surface of the flange 14 andthe shoulder 23 formed around the wall 16 adjacent to the top plate 18.

A tube 24 extends through and is formed integral with the compartment D,the upper end thereof extending above the top wall 18 and the lower endextending for a distance below the bottom wall 17. The lower end of thetube 24 is provided with a conical port 25 which is adapted toconstitute a seat for a conical valve plug 26 mounted upon a stem 27.The stem 27 is provided with a threaded enlargement 28 which cooperateswith a threaded portion 29 of the upper end of the tube 24'. The stem 27is bent at 30 providing a finger piece whereby the stem may be rotatedto raise and lower the valve plug 26 from its seat 25.

Through the walls of the tube 24 adja-icent to the inner face ofthebottom wall 17 are provided perforations 31 constituting ports for thepassageof fluidcontained in the compartment D into the tube. It willinto the compartment C upon the carbid conta ned in the bottom oi saidcompart- -ment, gas will be generated WllTCl] will pass outwardlythrough a tube 32, the outer end of which is equipped with a jet tip 33.

Within the tube 32 it is preferred to pro vide a quantity 34 of fibrousmaterial, for

instance cotton. to prevent the excessive passage of gas to the tip 33.

The containers C and D with the associated parts constitute anindependent gas generating means for the supply of gaseous fuel for thetip 33. 7

In order to prevent the passage 25 from becoming choked by anaccumulation of carbid or other chemical that might be used, the lowerend of the stem 27 is provided with a polygonal projection 35 so that,when the stem 27 is raised in the tube, the edges or the polygonalprojection will come in contact With the edges of the opening 25 andthereby remove the accumulations thereon.

Extending downwardly from the bottom wall 2 of the container A is atubular eXtension 36, the walls of which are bent to form threads. Acontainer E comprising an annular sidewall 37, a bottom wall 38 and atop wall includingan inclined portion 39 and a tubular neck 40 isadapted to be removably secured in association with the container A. Thetubular neck 40 is bent to form threads adapted to be received inthreaded engagement with the extension 36.

In order to provide a hermetic seal or joint between theextension 3.6and the compartment E a rubber washer or gasket 41 is mounted upon theportion 39 of the con tainer E and is adapted to be embraced betweensaid lnclined wall portion 39 and au' outwardly-flaring anddownwardly-extending flange 43 formed at the bottom of the tubularextension 36.

A tube 43 is mounted within and into grally formed with the compartmentB and extends'upwardly through the top wall 3, the upper portion thereofbeing threaded to receive an enlarged threaded portion 44 of a stem 45which is adapted to-be manipulated by a finger piece 46 formed at thetop'ot said stem. The stem 45 extends throughout the length of the tube43 which terminates; within the chamber E, sa-id'stem 45 carrying aconical valve plug 47 adapt ed to cooperate with a passage 48constituting a valve seat'therefor in the bottom of the tube 43.

The valve is operated similarly to the operation of the valve 2526 asheretofore described. "The stem 43 includes, as does the stem 27, apolygonal portion 49 for the purpose of removing accumulations upon theedges of the valve seat 18. The tube 43 has perforations 50 through thewall thereof within the compartmentB constituting passage ways for theliquid, from the compartment into the tube, which is delivered throughthe valve 4748 to the com artment E where it comes in contact with thechemical contained in said compartment generating gas in the mannerunderstood and as hercinbefore described.

A tubular extension 51 is provided with a jet tip 52 affording means forconducting the gas enerated in the compartment E to a point forconsumption. A piece of fibrous material 53, which is deflecteddownwardl over the opening between the tubular portion 51 and theopening in the extension 36, provides a porous wall preventing theexcessive passage of the gas from the jet 52.

It will hev noted that the jets 33 and 52 are in vertical alinement sothat the flame from the one maybe transferred to the other by fanningthe flame with the hand, or in ny suitable manner, the jets beingarranged sufficiently close to each other to permit ignition of the onejet from the other'in this manner. V

A reflector 54 provided with openings embraced by inwardly extendingflanges 55 and 56, respectively, is adapted to befitted in position toserve both jets, the flanges 55 and 56 engaging over the ends of thetubes 32 and 51 respectivel 7 This construction permits the reflector tobe removed or adjusted in position with facility.

I am aware that modifications in the details of construction -mav bemade without departing from the spirit and scope of the invention. I donot'desire to limit myself, therefore,,t o the exact details shown anddescribed, but what I claim and desire to secure by Letters Patent is 1.An acetylene lamp, comprising independent and optionally operable gasgenerating means,'and composed of a compartmei t divided into two nonommunicating chambers each adapted to contain a gas forninz material, aseparate removable compartment adapted to contain a gas forming materialto'cotiperate, with the material in one of said chambers, a passage foradmin ting the material from the removable compartment to the chambercontainingthecooperating material, an additional removable compartmentadapted to contain a gas form ing material to cooperate with thematerial in the other one of said chambers and adapted to be placed incommunication therewith, whereby gas may be independently and optionallygenerated, and a jet burner serving each source of gas generation.
